A couple of weeks back, I was testing a DHCP configuration scenario using a number of virtual machines and needed them to obtain their IP addresses from a Windows 2000 DHCP server within my virtual network. That should work, but for some reason, my virtual clients were picking up strange private IP addresses in the range 10.237.0.16-10.237.255.254 (not even the familiar automatic private IP addresses in the range 169.254.0.1-169.254.255.254). After a while, I discovered that Virtual Server has the capability to provide its own DHCP service and that this was enabled. By editing the configuration for the internal network I was using, I could disable Virtual Server's DHCP server, allowing my clients to locate the correct DHCP server.
